Description

Technical Field

[0001] The present invention relates to the technical field of annealing of aluminum enameled wires, and particularly to an annealing device for aluminum enameled wires. Background Art

[0002] At present, annealing is an essential process in the production of aluminum enameled wires. Most of the materials for aluminum enameled wires are copper wires. The purpose of annealing is to heat the copper wires, which have become hard due to lattice changes during the die stretching process, to a certain temperature, so that the molecular lattice is rearranged to restore the softness required by the process. At the same time, the lubricants, oil stains, etc. remaining on the surface of the copper wires during the stretching process are removed, making the copper wires easy to be painted and ensuring the quality of the aluminum enameled wires.

[0003] Existing annealing devices, such as the aluminum enameled wire annealing device disclosed in the patent publication number CN213835474U, have a copper wire passing through the annealing tube and entering the cooling pool. When the high-temperature copper wire meets water, water vapor is generated, and the water vapor flows along the annealing tube in the cooling pool to the heating tube, playing a role in preventing oxidation of the copper wire. However, due to the small wire diameter, the amount of water vapor generated when the high-temperature copper wire meets water is likely to be insufficient. Since the water vapor is light in mass, it is easy to accumulate in the upper cavity of the annealing tube, resulting in insufficient oxidation protection effect at the bottom of the copper wire. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an annealing device for aluminum enameled wires, thereby solving the problems existing in the prior art.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme:

[0006] An annealing device for aluminum enameled wires includes an annealing box and a cooling pool. An annealing tube is arranged in the annealing box. A coating device is arranged at one end of the annealing box, and the coating device is used for coating a protective liquid. An air extraction sleeve is slidably connected to the annealing tube. The annealing tube is arranged in a spiral distribution with a plurality of suction holes. A plug plate is arranged in the suction holes. A top rod is arranged on the inner wall of the air extraction sleeve, and the top rod is used to push the plug plate to open the suction holes.

[0007] The annealing box is provided with a driving device, and the driving device drives the air extraction sleeve to move axially along the annealing tube and rotate.

[0008] Preferably, an installation sleeve is fixedly connected to the inner wall of the air extraction sleeve. The top rod is slidably connected in the installation sleeve. One end of the top rod is spherical. A support spring is fixedly connected between the top rod and the bottom of the hole of the installation sleeve. The outer end of the suction hole is a tapered hole. A cross plate is arranged in the suction hole. The cross plate is slidably connected to a pressure rod. One end of the pressure rod is fixedly connected to a blocking plate. An arc-shaped convex block is arranged at the other end of the pressure rod. A first spring is fixedly connected between the arc-shaped convex block and the cross plate.

[0009] Preferably, the driving device includes two sliders slidably arranged towards each other. A cross bar is fixedly connected to one side of each slider. A suspension rod is fixedly connected to the bottom of the cross bar. A support sleeve is fixedly connected to the lower end of the suspension rod. An air extraction sleeve is rotatably connected inside the support sleeve.

[0010] Preferably, the two sliders are controlled to slide by a bidirectional lead screw-motor mechanism.

[0011] Preferably, arc-shaped blocks are arranged at intervals on the bottom of the inner cavity of the annealing box, and the heights of the spaced arc-shaped blocks gradually increase from the edge of the annealing box to the middle of the annealing box;

A toothed plate is slidably connected vertically to the support plate. The toothed plate meshes with the outer gear ring.

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Such as Figures 1 to 4As shown in the figure, an annealing device for aluminum enameled wire provided by the present invention includes an annealing box 1 and a cooling pool 2. An annealing tube 3 is arranged inside the annealing box 1. A coating device is arranged at one end of the annealing box 1, and the coating device is used for coating a protective liquid. The coating device is prior art, such as coating alcohol disclosed in the patent publication number CN213835474U. A suction sleeve 4 is slidably connected to the annealing tube 3. The annealing tube 3 is arranged in a spiral distribution with a plurality of suction holes 5. A plug plate 6 is arranged on the suction hole 5. A push rod 7 is arranged on the inner wall of the suction sleeve 4, and the push rod 7 is used to push the plug plate 6 to open the suction hole 5;

[0021] A driving device is arranged on the annealing box 1. The driving device drives the suction sleeve 4 to move axially along the annealing tube 3 and rotate. A suction pump is arranged outside the annealing box 1, and an air suction hose is arranged between the suction pump and the suction sleeve 4.

[0022] In the present invention, air is suctioned through the moving suction sleeve 4, so that steam gathers and fills in the middle of the annealing tube 3. During the movement of the suction sleeve 4, the suction holes 5 in different positions are sequentially opened, so that the steam surrounds the aluminum enameled wire in the annealing tube 3, thereby achieving a better oxygen isolation effect and avoiding the defect that steam accumulates at the top wall position of the annealing tube 3.

[0023] As a specific embodiment of the present invention, an installation sleeve 71 is fixedly connected to the inner wall of the suction sleeve 4. The push rod 7 is slidably connected in the installation sleeve 71. One end of the push rod 7 is spherical. A support spring 72 is fixedly connected between the push rod 7 and the bottom of the hole of the installation sleeve 71. The outer end of the suction hole 5 is a tapered hole, which is convenient for the push rod 7 to enter and leave the suction hole 5. A cross plate 52 is arranged in the suction hole 5. The cross plate 52 is slidably connected to a pressure rod 53. One end of the pressure rod 53 is fixedly connected to a blocking plate 54. An arc-shaped convex block 55 is arranged at the other end of the pressure rod 53. A first spring is fixedly connected between the arc-shaped convex block 55 and the cross plate 52.

[0024] The suction holes 5 are arranged in a spiral distribution. When the suction sleeve 4 moves along the annealing tube 3 and encounters a deflected suction hole 5, the suction sleeve 4 controls the rotation. When the push rod 7 encounters the suction hole 5 in the moving path, the push rod 7 is pushed into the suction hole 5 by the support spring 72, and the arc-shaped convex block 55, the pressure rod 53 and the blocking plate 54 are pushed towards the inside of the annealing tube 3, so that the originally blocked suction hole 5 changes to play a role in air suction and circulation. On the one hand, through the sequential opening of the suction holes 5 in different positions (when the suction sleeve 4 moves towards the middle of the annealing tube 3, the suction pump is turned on, and when the suction sleeve 4 retracts, the suction is turned off), the steam is guided towards the middle of the annealing tube 3, and the position where the air flow is attracted surrounds the aluminum enameled wire (as Figure 4 shown), so that the steam can surround and wrap the aluminum enameled wire; compared with a separate air suction device arranged in the middle of the annealing tube 3, it avoids the shortage of steam volume and the deficiency that the steam can only move along the top wall of the annealing tube 3 (the principle of the shortest path of air flow).

[0025] As a specific embodiment of the present invention, the driving device includes two sliders 8 arranged to slide toward each other, and the two sliders 8 are controlled to slide by a bidirectional screw-motor mechanism. The bidirectional screw-motor mechanism is a prior art, which controls the two sliders 8 to move closer to or away from each other. One side of each slider 8 is fixedly connected to a cross bar 81, and the bottom of the cross bar 81 is fixedly connected to a suspension rod 82. The lower end of the suspension rod 82 is fixedly connected to a support sleeve 83, and the support sleeve 83 is rotatably connected to the exhaust sleeve 4.

[0026] The bottom of the inner cavity of the annealing box 1 is provided with arc blocks 84 at intervals, and the height of the arc blocks 84 increases gradually from the edge of the annealing box 1 to the middle of the annealing box 1, and the aperture of the suction hole 5 increases gradually from the edge of the annealing box 1 to the middle of the annealing box 1. The larger the aperture of the suction hole 5, the easier it is to evacuate air. The suction hole 5 with the largest aperture is provided in the middle of the annealing tube 3, so that the steam surrounding the aluminum enameled wire can be quickly evacuated, so that the annealing tube 3 is continuously filled with steam to prevent oxidation.

[0027] The exhaust sleeve 4 is fixedly connected to the outer gear ring 85, and the side of the cross bar 81 is fixedly connected to the support plate 86. The support plate 86 is vertically slidably connected to the tooth plate 87. The tooth plate 87 is meshed with the outer gear ring 85. The tooth plate 87 vertically slides through the outer gear ring 85 to push the exhaust sleeve 4 to rotate. A second spring 88 is fixedly connected between the tooth plate 87 and the support plate 86. The side of the tooth plate 87 is rotatably connected to the pressure wheel 89. The pressure wheel 89 is set corresponding to the arc block 84, and the arc block 84 is set corresponding to the position of the suction hole 5.

[0028] In this embodiment, the two sliders 8 move toward each other to gather the steam at both ends of the annealing tube 3 toward the middle, thereby compensating for the defect of insufficient anti-oxidation effect caused by insufficient steam; the exhaust sleeve 4 slides along the annealing tube 3, and the pressure wheel 89 rolls at the bottom of the inner cavity of the annealing box 1. When the pressure wheel 89 rolls to the corresponding arc block 84, the tooth plate 87 is pushed up, and the tooth plate 87 rotates and pushes open the exhaust sleeve 4 to the suction hole 5 in the corresponding direction through the outer tooth ring 85. By changing the suction direction, the steam is guided to surround the aluminum enameled wire, and through the arc blocks 84 of different heights, the deflection angle of the exhaust sleeve 4 is gradually increased, so that the steam fills the annealing tube 3, thereby achieving a better anti-oxidation effect.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
